The isochoric heat capacity of the n-hexane–water system was studied on an adiabatic calorimeter at 300–600 K and molar fractions of water of 0.256–0.935 in a wide range of densities. The experimental critical curves of the liquid–vapor phase equilibrium were described by the equation corresponding to the theory of critical phenomena.
